Description
Technical field
The invention belongs to biomolecule pharmaceutical technology field, and in particular to a kind of injection aquagel and its preparation and should
With.
Background technology
Hydrogel is the three-dimensional net structure by high molecular crosslink, in biomedicine field such as insoluble drug release, organizational project
Had a wide range of applications with bio-sensing etc..In minimally invasive medical and injectable organizational project, Injectable in-situ gel system by
Extensive concern is arrived.Gel-in-matrix before the injection by biomolecule or mixing with cells in the solution, through injection can will bear
The timbering material for having carried biomolecule or cell is implanted to and needs position, after gelation, becomes and is released for the medicine in pharmaceutical preparation
Put basic point or the cell growth basic point of regeneration, it is to avoid operation implantation it is painful and cumbersome, and cells in situ fixation also has
Beneficial to one irregular tissue defects of filling.
At present, preparing the method for situ-gel system has chemical crosslinking and is physical crosslinking, and chemical crosslinking includes radical polymerization
Conjunction and Michael's addition etc., it usually needs add initiator or generation small molecule by-product, physical crosslinking passes through physical change bag
Include the change realization such as pH value, temperature and ionic strength.The hydrogel (i.e. dynamic key gel) constructed using dynamic covalent bond is had
Higher mechanical strength and syringeability, and because sensitive group is chemical bond, so as to greatly widen optional macromolecule material
The scope of material, can construct the hydrogel with multiple response.Poplar etc. can construct pH/ temperature sensitives using saccharin key
Injectable chitosan matrix hydrogel, saccharin key has physiological pH response, can trigger gel by adjusting pH value
Formation and destruction, it is not necessary to initiator, and the small molecule product of the reaction is water, it is to avoid impurity draws in gel process
Enter;The hydrogel of formation has preferable mechanical strength, and at macromolecule content relatively low (5.0wt%), its modulus of elasticity is reachable
103-104Pa, the hydrogel can be used for the long-acting controlled release of antineoplastic, and achieve preferable oncotherapy effect
(Dually Responsive Injectable Hydrogel Prepared by In Situ Cross-Linking of
Glycol Chitosan and Benzaldehyde-Capped PEO-PPO-PEO,Biomacromolecules 2010,
11,1043-1051).Borate ester is reacted by phenyl boronic acid derivative and polyol to be formed, and reaction does not need initiator,
Do not produce other accessory substances than water, with glucose oxidase (GOx), agglutinin be construct glucose responding system three
Big system.Glucose oxidase and agglutinin are protein compound, and harsher to environmental requirement, the change of external environment can
It can be caused to inactivate, limit its application.And the diversity and more preferable stability that imine linkage is designed due to it, in development Portugal
There is larger advantage in terms of grape sugar Response System, cause researchers and more widely pay close attention to.There is document report by benzene boron
Gel and microgel that acid and NIPA (PNIPAM) are constituted, can be swelled and release in the presence of glucose
Release insulin, but these materials ability only under higher than phenyl boric acid pKa value (pH 9) and higher concentration of glucose (20g/L)
With glucose responding, the application of its (pH 7.4, concentration of glucose 1-3g/L) in physiological conditions is limited

The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of biodegradable injectable water-setting of safety non-toxic
Glue, the aldehyde radical shape of the amino and butyraldehyde-polyethylene glycol-butyraldehyde of the main polyethylene glycol using the modification of the arm Amino End Group of specific structure four
Into imines dynamic key obtain syringeability hydrogel.
It is easy, quick with preparation process, it is easy to big present invention also offers the preparation method of the injection aquagel
The advantage of large-scale production.
The concrete technical scheme that the present invention takes is as follows:
A kind of injection aquagel, is constituted by raw material A, raw material B and into glue;The quality sum of the raw material A and raw material B
Mass percent in hydrogel is 5%-50%, and wherein raw material A is butyraldehyde-polyethylene glycol-butyraldehyde, and raw material B is four arm ends
Amido modified polyethylene glycol;
The structural formula of the butyraldehyde-polyethylene glycol-butyraldehyde is as shown in formula I:

Injection aquagel of the present invention, using four arm Amino End Groups shown in butyraldehyde-polyethylene glycol-butyraldehyde shown in formula I and formula II
The polyethylene glycol of modification, both structures are the macromolecular with good aqueous solubility, the polyethylene glycol of four arm Amino End Groups modification
In four arm configurations the network with hydrophilic soft segment, butyraldehyde-polyethylene glycol-butyraldehyde can be provided for hydrogel
Linear chain structure also act as soft segment, both distinctive structures ensure that the hydrogel to be formed has in aqueous
Porous and fine and close structure, obtained hydrogel has excellent flexibility and elasticity, and slow release effect is controllable;Meanwhile, four arm ends
The amino of amido modified polyethylene glycol and the imines dynamic key of the aldehyde radical formation of butyraldehyde-polyethylene glycol-butyraldehyde have to pH rings
Ying Xing, can be formed in situ the gel that uniform state is presented, can be implanted by injection system.
Consider raw material A and the specific chemical constitutions of raw material B, in order to reach more preferable invention effect, preferably:
The raw material A and raw material B mass ratio are (0.5-25):1, the stability and injectable of hydrogel can be strengthened
Property.
The mass percent of the raw material A and raw material B quality sum in hydrogel is 5%-30%, further preferably
For 5%-20%, most preferably 5%-15%.When raw material A and raw material B gross mass percentage concentration is 5%-20%, injectivity is more
It is excellent;When raw material A and raw material B gross mass percentage concentration are more than 20% and are less than or equal to 50%, the stability of gel is more preferable.It is former
When the gross mass percentage concentration for expecting A and raw material B is 5%-15%, not only injectivity is excellent, and preferably in human normal body
Quick-gelatinizing under the conditions of warm scope (general 36.0 DEG C -37.5 DEG C) and normal physiological pH7.4.The present invention can be according to hydrogel
Application field is different, selects suitable raw material A and raw material B gross mass concentration range.
It is described to select deionized water or pH value in 6-8 cushioning liquid into glue, provide plastic environment for hydrogel.
The cushioning liquid can using disodium hydrogen phosphate-citrate buffer solution, potassium dihydrogen phosphate-sodium hydrate buffer solution,
Disodium hydrogen phosphate-phosphate sodium dihydrogen buffer solution, barbital sodium-hydrochloride buffer, three (methylol) aminomethane-hydrochloride buffers
(Tris-HCl buffer solutions), boric acid-borate buffer solution, Glycine-NaOH buffer solution, borax-sodium hydrate buffer solution, carbon
One or more in the cushioning liquid such as sour sodium-sodium bicarbonate buffer liquid.
According to the requirement of its application field, it is described can select into glue it is sterile into glue.
The preparation method of the injection aquagel, including step:
Raw material A and raw material B addition glues are well mixed, injection aquagel is obtained.
The formation temperature of the injection aquagel is at 20 DEG C -38 DEG C.
